Your new results type is a list of dicts.
Lists are indexed by a number. That will be results[1] for the dict
relevant to "gengyang" (not even the 2 of the "id", because lists start
counting at 0).
To find the entry for particular name, you have to search for it (for a
list entry where the dict key "name" gives you the value you expect, ie.
"gengyang" in this example).
So a dict of dicts was a better idea.
